Opinions or advice (kind of long)

[Boomer!]

Well the last few months have been crappy for me but things are looking better, sort of!!!

Here is my problem for he last month or two my old lady has changed ( for the worse ). Constant attitude to me and screaming at the kids, we have talk over and over again about with no results. I have noticed that her leaving for shopping trip are increasing as well as time she is gone. Multiple text messages when she is home and she always goes in another room to use the phone. She continues to talk about some guy she works with in her sleep, when I confronted her she says "nobody by that name works with her" yet I hear here talk about him here and there. Lately she has been asking me for stuff, new car, a new ring and to pay off some of her bills and get married. When her and I met she told me why her and her a ex didn't work out and now I'm seeing the signs of the same things she did to him.

I have talked to a few buddies and they have their opinions, but I'm still unsure of what to do.

Most of them think she is going to take everything she can get and run, I don't know. Am I just blind ????

Any opinions or advice, please I won't get offended...
